One of Griffin's favorite commercials is the Kellogg's Raisin Bran commercial where they three guys talk about what their favorite part of the cereal is. One of them points out that the middle part of "Kellogg's" is "ello," as in "'ello, guvnah!" with the appropriate British accent. We regularly find him walking up and down the halls saying it.
Well, in fourth grade, they study state governments and, unbelievably, Griffin was the first "Governor" of his class. So we took advantage of the opportunity to say to him regularly that week, "'ello, Guvnah!" when we talked to him.
